CONCLUSION QUESTIONS nts normally subjected to equivalent light intensities? What environmental can you think of in other regions? 2. What is the relationship between photosynthetic rate and light intensity? 3. Would a plant illuminated with green light be able to perform pho or why not? 4. What is the principle of paper chromatography as a separation technique? What is the relationship between sample concentration and sample absorbance? 6. What is the relationship between a sample's absorbance and transmittance? 7. Compare the split spectrum to your absorbance versus wavelength graph, how can you relate them?Explanation / Answer
Answer:
No, every plant has differentiating need of light intensity for its optimal survival, growth, development and yield.
Following are the environmental variations could be attribute in other region:
2. What is the relationship between photosynthetic rate and light intensity?
Answer:
Light is an essential part of plant life cycle. However, both deficient and excessive light intensities are injurious.
At low light intensities, rate of photosynthesis is directly proportional to light intensity as long as other factors are in adequate supply. The more photons of light that exposed on a leaf, the higher the number of chlorophyll that are ionised and the more ATP and NADPH are biosynthesised.
As light intensity is increased further, however, the photosynthetic rate can eventually limited by some other factor. So the plateaus phase of rate occur. At very high light intensity, chlorophyll may be damaged and the rate drops steeply.
3. Would a plant illuminated with green light be able to perform Photosynthesis effectively? Why or why not?
Answer:
Most plants reflect more green than any other in the visible spectrum, a relatively small percentage of green light is transmitted through or reflected by the leaves. Red and blue light is the most efficient wavelengths in photosynthesis as it can absorb by green chlorophyll molecule in leaf. However, this green color molecule reflect the green light.
Green light is the least efficient in the visible spectrum for photosynthesis, but it is still useful in photosynthesis and regulates plant growth.
6. What is the relationship between a sample absorption and transmittance?
Answer:
Sample absorption is the ratio of the light energy falling on a sample to that absorbed through it.
Sample transmittance is the ratio of the light energy falling on a sample to that transmitted through it.
So the sample absorption is inversely proportional to sample transmittance. It means higher the sample absorption, lower the sample transmittance.
